1. 21. Laminar Burning Velocity and Development of a Chemical Kinetic Model for Small Oxygenated Fuels

   Författare :Moah Christensen; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oxygenated fuels; Kinetic mechanism; Validation; Sensitivity; Laminar burning velocity; Heat flux method; Fysicumarkivet A:2016:Christensen;

   Sammanfattning : The thesis work was performed with the aim of increasing knowledge and understanding of the combustion of oxygenated fuels and intermediates. This was accomplished in two steps: experimental measurements of the laminar burning velocity to expand current databases and development of a reaction mechanism. LÄS MER

3. 22. Dynamic effects on yacht sails and rudders

   Författare :Adam Persson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Sailing dynamics; towing tank; sail aerodynamics; rudder; verification; validation; RANS;

   Sammanfattning : In search of increased performance, modern sailing vessels are becoming more and more complex, introducing additional challenges in the design process. The dynamic behaviour of the vessel is of great importance to safe and efficient operation and thus needs to be accounted for when evaluating the performance. LÄS MER

4. 23. Benefits of Pharmacometric Model-Based Design and Analysis of Clinical Trials

   Författare :Kristin E Karlsson; E Niclas Jonsson; Mats O Karlsson; Anders Grahnén; Michael K Smith; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; model-based analysis; pharmacometrics; modeling; disease progression; NONMEM; SAEM; Importance sampling; repeated time-to-event; RTTCE; RCEpT; NIH stroke scale; Barthel index; internal validation; external validation; study power; study design; PHARMACY; FARMACI; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

   Sammanfattning : Quantitative pharmacokinetic-pharmacodynamic and disease progression models are the core of the science of pharmacometrics which has been identified as one of the strategies that can make drug development more effective. To adequately develop and utilize these models one needs to carefully consider the nature of the data, choice of appropriate estimation methods, model evaluation strategies, and, most importantly, the intended use of the model.

5. 24. A Numerical Study of the Fluid Dynamics of Bubbling Fluidized Beds

   Författare :Hans Enwald; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; validation; two-phase solver; multiblock; statistical bubble parameters; parallelization; bed expansion ratio; bubbling fluidized bed; two-fluid model;

   Sammanfattning : The two-fluid model was evaluated as a tool for predicting local flow behaviour in bubbling fluidized beds. A review is given of the two-fluid model approach for simulation of the flow in bubbling fluidized beds. LÄS MER

7. 25. Single Base Station mmWave Radio Positioning, Mapping, and SLAM

   Författare :Yu Ge; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DA; positioning; 5G; experimental validation; RFS; SLAM; fusion; mmWave; diffuse multipath; mapping; single BS;

   Sammanfattning : Fifth-generation (5G) communication systems in Frequency Range 2, operating above 24 GHz and utilizing mmWave signals, showcase distinct properties that open up new possibilities in positioning, mapping, and simultaneous localization and mapping (SLAM). The combination of large bandwidth, extensive antenna arrays, and high carrier frequency results in geometric-based signals, and unprecedented delay and angle resolution. LÄS MER
